Ice making device, refrigerator and control method of refrigerator

Abstract

The invention discloses an ice making device, a refrigerator and a control method of the refrigerator, and relates to the technical field of electric appliances. The ice making device comprises a water storage box, a first pipeline, a second pipeline, an ice making fan and an ice making mold, the first pipeline and the water storage box form liquid path communication, and the second pipeline is arranged on the outer surface of the first pipeline and matched with the first pipeline to form an ice making air channel. And the ice-making fan is communicated with the second pipeline gas path. An ice-making cavity and an ice-making air cavity are formed in the ice-making mold, the ice-making cavity is communicated with the first pipeline liquid path, and the ice-making air cavity is communicated with the second pipeline air path. Moreover, when the ice-making fan works, refrigeration air is fed into the ice-making air cavity, and water in the ice-making cavity is slowly and uniformly cooled, so that the water in the ice-making cavity is low in cooling speed and small in temperature fluctuation and reaches a supercooled state. And the supercooling state is destroyed in the cooling process, so that the inside and outside of the center of the ice-making cavity are iced at the same time. Therefore, the transparency of the ice cubes can be improved, and the transparency requirement of users on the ice cubes is met.
